TO ALL WHOM IT MAY CONGERN:

Be it known that I, DAVID W. MARSTON, of Lebanon, in the county' of Graftomvand State of New Hampshire, have invented a new and useful Improvement in the Method of Uniting Scythes and Snaths with each other; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification- Figure 1 being a plan of my improvement as seen from the under side of the heel of a snath.

Figure'2, a section in' the linea: :1; of fig. 1.

Figure 3, anv end view ofthe heel of a snath which has my improvement combined therewith, and

Figure 4 is a view of the shanked ferrule B B', detached from a. snath.

Thesame letters refer to corresponding parts in all the figures.

I give the usual shape to thc heel-portion F, of a snath, and then place upon the same a closely-fitting ferrule, B, as shown in fig. 3. A Hat-faced shank, B', extends inwards from the Hat side of the ferrule B, and covers the flat portion of the.snath-heel, as shown in the drawings. An enlarged hole, h, is formed in the i'lat side of the ferrule B, and a smaller hole,j, is formed inthe opposite,vor curved side of the sameJ as shown in iig. 4. A square hole, m, is' also formed near the end of thc shank B', of the ferrule B, as also shown in fig. 4. The straight shank E, of a Scythe, is .securedto the plate A, which is itself secured upon the fiat side of the fel-rule B and its shank B', in the manner shown in fig. 2, viz, the projection from the under side of the plate A, tits into the enlarged aperture z, in the Hat side of the ferrule B. The pivot-bolt C passes through the Scythe-shank, then through an aperture in the centre ofthe projection lz', of the plate A, then through an aperture in the snath-h'eel, und then out through the aperture j, in the centte ofthe curved portion ofthe ferrule B, Where it may bc'secured by a screw-nut,f, asV shown in the drawings, or it may be secured by any other means' that may be" preferred. Near the inner end of the plate A, a slightly curved transverse slot, 7c, is formed, which receives the square portion of the bolt D, which passes through the square aperture m, in the ferrule-shank B', and then the shank of said bolt passes through an aperture in the snath-hcel, where its extremity may be secured by the scrcwbolt g, or by any other means that may be preferred. The` straight Scythe-shank E is received into a transverse recess formed by the parallel ledges e c, as 'shown in fig. 2. Suicicnt play of the scythefshank is allowed the aforementioned recess on the-plate A to allow the position of the edge of the seythe tobe adjusted up or down to any position required by the mower. The aforementioned slot 7c, in the plate A, permits the position of the point of the Scythe to be adjusted outwards 'or inwards, as may be required by the mower. Any desired length may be given to the ferrule-shank B', and also to the plateA. The sliding of the plate A beneath the head of the holt D maybe prevented by means of corrugations on the upper side of said plate, and corresponding corrugations on theiuner--face of the head of'saidbolt.

What I claim as my invention, and desire to secure by Letters Patent, is-f v AA straight Scythe-shank, when the said shank is connected to the heel of a snath by means of the transversely recessed and siotted plate A, the shanked ferrule B B', the pivot-bolt, and the holding` .bolt D, substantially in the manner herein represented and described. u i

I also claim the combination of the transversely recessed and slotted plate A, and the shanked ferrule B B', with each other, and'with the heel of a snath, by means of the pivot-bolt C and the holding bolt D, substantially 'ashcrein represented and described.' I A ,The aforegoing specification `o f my new anduseful improvement in the method ofuniting scythes and snaths with each other, signed and witnessed this 6th day of August, 1866. i Y
